firmoss

Huperzia is a genus of Lycophyte plants, sometimes known as the firmosses or fir clubmosses. This genus was originally included in the related genus Lycopodium, from which it differs in having undifferentiated sporangial leaves, and the sporangia not formed into apical cones. The common name firmoss, used for some of the north temperate species, refers to their superficial resemblance to branches of fir (Abies), a conifer. In Australia, the epiphytic species are commonly known as tassel ferns.
